Saiki in his human form is the penultimate boss in Story Mode and a challenging opponent in Arcade Mode. He possesses a unique moveset based on dark energy, featuring fast attacks, a teleport, and a dangerous command grab. His AI is aggressive and can punish mistakes severely.

Phases & Attacks:
- Phase 1 (Normal): Saiki uses a fast projectile (
236P), a teleport (214K), a dive kick (j.214K), and a command grab (632146P). His normals have good reach and priority. - Phase 2 (Power-Up): After taking a certain amount of damage, Saiki will glow red and gain increased attack power and speed. His special moves may have enhanced properties.
Weaknesses & Strategies:
- Punish Teleports: Saiki's teleport has a slight recovery. Anticipate his landing and punish with a quick combo.
- Watch for Command Grab: His command grab is slow but powerful. Jump or backdash when you see him winding up for it.
- Block and Counter: Saiki's strings can be long. Block them and look for openings after his special moves, especially his projectile.
- Anti-Air Dive Kicks: His dive kick can be tricky, but a well-timed anti-air special move will knock him out of the air.
- Meter Usage: Don't be afraid to use your Super Special Moves or Neo Max Super Special Moves during his power-up phase to deal burst damage and shorten the fight.
Patience and precise blocking are key. Don't rush in blindly, as Saiki will punish over-commitment. Observe his patterns and strike when he leaves himself vulnerable.
